Title: Improvements relating to range finders
Inventor: EVEREST FRANK GEOFFREY
IPC: G01S17/18
Filed: 1968-03-06
Abstract: 1,204,008. Lasers. BRITISH AIRCRAFT CORP. Ltd. 4 March, 1969 [6 March, 1968], No. 10958/68. Heading H1C. [Also in Divisions H3-H5] Specification describes a pulsed laser range finder wherein the laser echo is sought by a walking gate produced by comparison between slow and fast ramp voltages and said gate becomes locked on to the echo on aquisition. The laser 4, Fig. 2, is pulsed by generator 13 (trigger pulses (b), Fig. 3). Pulses (b) also trigger monostable circuit 17 to produce waveform (g). An integrator circuit 18 produces the fast ramp voltage (a), defining the maximum detectable range interval by the duration of the ramp. The laser pulse echo is received by detector 10 and the resulting electrical pulse is fed via amplifiers 14 and 15 to early/late gate assembly 16. In the search mode a range integrator 20 is fed with a steady current from generator 27 and produces a slow ramp of period 1 sec. This is compared with the fast ramp voltage (a) in comparator 21 and the output thereof is a pulse (c) commencing at the time of equality of said two ramps, said time advancing from pulse to pulse. The commencement of pulse C generates early and late gates (d) and (e) of 250 nsec. duration which are fed to assembly 16. Capture of the echo by either of these gates produces an output of appropriate polarity which, via differential amplifier 23, produces an error signal correcting the output of integrator 20 such that the next echo pulse tends to fall half in the early gate and half in the late. Such a system results in the output of the integrator 20 having a sawtooth component. To overcome this a 500 nsec. gate is produced by combining the early and late gates and is used to gate through the captured pulse in gate 25. When a predetermined number of pulses have been so gated, detector 26 produces an output which stops the current flow from generator 27 to the integrator 20. The integrator output thus becomes constant and representing range may actuate a motor 32 whereby enabling a digital range read out at 33 and the movement of a lens 5, Fig. 1, in the projection optics of the laser beam, whereby the cross-section of the beam is always 1 metre square at the target. A sighting grid 11 in the eyepiece of a visual pointing system 10 may also be automatically moved to be always simultaneously in focus with the target. The integrator 20 is periodically clamped by pulses (f) produced by delaying the output of circuit 17.

Abstract: 1391072 Developing silver halide materials EASTMAN KODAK CO 9 March 1972 [10 March 1971] 10979/72 Heading G2C A method of making a direct positive image comprises imagewise exposing an unfogged silver halide emulsion in which the grains contain occluded polyvalent metal ions and which contains a 'desensitizing concentration' of a sensitizing dye i.e. a concentration which lowers the blue-speed of a surface sensitized emulsion, selectively surface fogging the unexposed grains and developing the fogged grains with a surface developer. The polyvalent metal ions may be Pb, trivalent Bi, Au, Ir, Rh, Sb, or As, or tetravalent Os, Ir or Pt. The fogging may be achieved by exposing the layer overall to light during development, heating the layer to a temperature of 100C prior to development or treating the grains with a fogging agent e.g. hydrazine or an N-substituted cycloammonium salt, which may be incorporated in the emulsion layer in a water-permeable layer adjacent thereto, or in the surface developer. A material which may be used for the method comprises an emulsion incorporating the dye and in which the unfogged grains containing the occluded ions are monodisperse. There is also disclosed a film unit for a diffusion transfer process comprising an emulsion layer comprising unfogged grains with occluded ions and the dye, an image receiving layer and a processing composition, the unit containing a fogging agent which contacts the emulsion layer during processing.

Examples of X are acyloxy, e.g. acetoxy, hemisuccinate ester, ethyl carbonate ester, diethylaminoethyl ether, alkyl ether, e.g. methyl ether, monophosphate ester or carbamate ester groups. Thus compounds in which X is an ester group, such as acyloxy, may be formed by reacting the chromenol with a mono or polybasic organic or inorganic acid or its acid halide or anhydride. Compounds in which X is an etherified hydroxy group may be obtained from a compound in which X is OH or ONa by reaction with an alkylhalide or, e.g. diethylaminoethyl halide. Where X is a phosphate ester, a compound where X is OH is reacted with Cl.P(O)(OCH 2 C 6 H 5 ) 2  to form an intermediate [X=-O-P(O)(OCH 2 C 6 H) 2 ] which is catalytically hydrogenated to yield a compound in which X is -OP(O)(OH) 2  which can be obtained in Na salt form. Pharmaceutical compositions, useful as antidepressants, anti-anxiety agents, hypotensives and analgesics, comprise compounds of Formula (I) above together with pharmaceutical diluents in forms suitable for administration orally or by injection.
